Refurbishment Order with serial number

I would like to ask about refurbishment order with serial number.
The first, I want to take this equipment to warehouse using GR., and the I input
material, serial number, and valuation type C3 (damage).
But when I save this document, I have found error "Batch for serial number 14
(C1) differs from document batch C3".
I check equipment master on serial data tab, on the field master batch is C1. I
change C1 become C3 and after that I GR this material not found problem.
My question, whether we should change valuation type at equipment master become
C3 before GR this material?
Can we do GR without change valuation type at equipment master? I means
automatic change status valuation type become C3.
And I don't want to used enhancement using abap program.
Any idea about this problem?

When I want to receive the material into warehouse using MIGO, I have the
problem about valuation type.
In the MIGO, I input material, serial number and valuation type C3 (damage), but
result is error valuation type.
Cause status the material that link to equipment have valuation type is C1 (good
material) in tab serial data on equipment master.
So, I must change valuation type first from C1 to C3 and then MIGO proses can be
done.
My question, can we receive material without change valuation type from C1 to C3
at equipment master?

We set up a user exit to clear the valuation in the equipment record when the material is shipped to a customer. Then if the material is received back from the customer the valuation in the equipment record does not prevent us from receipting it into the warehouse.

This exit happens when the movement is posted. We check whether it is a 261 to a service order then check if it is a serialized split valued part. If it is, we clear out the valuation in the equipment record. If you are shipping via a delivery something similar can be done in a user exit for when a delivery is posted.
